+## ✔ IMAGE ENCRYPTION DECRYPTION
+- An Image Encryption Decryption is an image processing application created in python with tkinter gui and OpenCv library.
+- In this application user can select an image and can encrypt that image to gray scale image and can even decrpyt also.
+- Also after encrypting and decrypting user can also save the edited image anywhere in the local system.
+- Also there is option to reset to the original image.
+
+****
+
+### HOW TO Use it :
+- User just need to download the file, and run the image_encryption_decryption.py, on local system.
+- After running a GUI window appears, where user needs to choose an image file using CHOOSE button on the top right corner.
+- After selecting the image, two images will appear on screen one on left side, which is original and one on write in which Encrypted Decrypted format will be shown.
+- Now user can start encryption and decryption using Encrypt and Decrypt button.
+- After editing user can also save the edited image to any location in local system using SAVE button.
+- Also there is a RESET button, clicking on which resets the edited image to original format.
+- Also there is exit button, clicking on which we get a exit dialog box asking the permission to exit.
